DUMP-TAB LE Specification of Letters Patent.

Application filed March 25, 1907. Serial No. 3134.475.

Patented Nov. 5, 1907.

To all whom it may concern:

Be it known that l, FRANK S. PEGK, of Menomonie, Dunn county, Wisconsin, have invented certain new and useful Improvements in Dump-Tables, of which the following is a specification.

My invention relates to apparatus designed particularly for use in brick yards, and the object of the invention is to provide convenient means for delivering the pallets loaded with brick to the conveyer whereon the pallets are transported to the drying racks.

My invention consists generally in a conveyor, a pivoted shelf or table whereon the loaded pallets are placed, and means for delivering the pallets to the conveyer.

Further, the invention consists in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation oi a dumping table or stand embodying my invention. Fig. 2 is a top view of the same. Fig. 3 is a vertica sectional view illustrating the loaded pallet raised above the level of the conveyer. Fig. 4 is a detail view illustrating the manner of delivering the loaded pallet to the conveyer. Fig. 5 is a transverse sectional view looking toward the end of the table or stand.

In the drawing, 2 represents upright posts or standards, preferably of tubing, and 3 and 4 pipes extending forwardly from saidstandards at different elevations and braced and supported by pipes 5, 6 and 7 The pipes 3 are provided with blocks 8 and 9 adjustably mounted thereon and having slots 10 in their upper ends wherein brackets 11 are adjustably secured, carrying sheaves 12 over which the power-operated cables 13 pass. Blocks 14 are mounted on the pipes 4 and carry sheaves similar to those described. The adjustment of these blocks and sheaves permits the tension of the cables to be regulated as desired.

Within the hollow standards pipes 15 are arranged, connected at the top and bottom by cross bars 16 and 17. A table or plate 18 is hinged at 19 on the cross bar 17 and has a ledge 20 at one side, and the top of said table is normally below the upper section of the cables 13 and the weight of the ledge on the table causes it to normally occupy a substantially vertical position, as indicated in Fig. 1. Near the standards is a platform 21 having a board 22 therein hinged at 23 and connected bya strap 24 with the cross bar 16. A loop 25 has its ends attached to said bar and a rod 26 adjustably connects said loop with an arm 27 on the cross bar 17. When, therefore, the free end of the board 22 is depressed the cross bar 16 and the pipes connected therewith, will be moved vertically and the table will be lifted also, so that its upper surface will. be above the level of the moving conveyer.

To use the apparatus, a pallet is placed on the table with one edge resting on the ledge, and the'attendantwill place a mold filled with brick upon the ledge and removing the mold leave the brick on the pallet. During this operation the table will swing on its pivots and assume a substantially horizontal position held by the Weight of the pallet and the bricks, and as the operator has depressed the board 22 in placing the brick on the table, thesupports of the table will be raised and the pallet lifted above the level of the conveyers. As soon, however, as the operator turns away from the platform and removes his foot from the board 22, the parts will immediately return by gravity to their normal position and the loaded pallets will drop down su'lliciently to be engaged by the conveyers while the table will pass down between the conveyers and return automatically to its normal position. The operation described may then be repeated. Whenever desired the adjustment of the rod 26 with the loop 25 may be changed to vary the movement of the table.

I claim as my invention:

1. The combination with a suitable frame having sheaves, of cable conveyors operating over said sheaves, a vertically moving table arranged between said conveyers and normally below the level of the upper section of said conveyors, said table being adapted to receive loaded pallets of brick, the pallets projecting beyond the ends of the table, and means for raising said table to lift it and the pallet thereon temporarily above the level of said cables, and said table returning by gravity when released, to its normal position to deposit the pallet upon the tables, substantially as described.

2. The combination, with the power operated cables, of

a pivoted table adapted to receive a pallet loaded with brick, said table being normally in a substantially vertical position and adapted to swing to a horizontal position between said cables and below the level of the top of the same, means for raising said table above the level of the upper section of said cables, and the ends of the pallets projecting beyond the ends of said table, whereby when said table is released and returns to its normal position between said cables, the pallet will be automatically delivered to said cables, substantially as described.

3. The combination, with a suitable frame, of sheaves mounted therein, power-operated cables passing over said sheaves, a vertically moving frame, a pivoted plate connected with said frame and adapted to lift the same when weight is applied thereto, a hinged table carried on said frame between said cables and having a ledge at one end and normally being in an inclined position to receive the loaded pallets ofbrick and adapted to swing to a substantially horizontal position between said cables and below the level of the upper portion thereof, and said frame when elevated raising said table above the level of said cables, and whereby the loaded pallets placed on said table and raised above the level of said cables will be deposited thereon when the weight is removed from said plate, and said table returns to its normal position.

4. The combination, with a frame, of a conveyer operating therein, a vertically moving table normally below the level of the upper section of said conveyer and adapted to receive loaded pallets of brick, the pallets projecting be:

yond the ends of said table, means for raising said table to lift it and the pallet thereon above the level of said conveyer, and over the upper section thereof, whereby when the said table is returned to its normal position the said 5 pallet will be deposited upon said conveyer.

5. The combination, with a frame having sheaves mounted therein, of cable conveyers operating 'ovc'r said sheaves, a vertically moving table arranged between said conveyers and normally below the level of the upper por 10 tion thereof, said table being adapted to receive' loaded pallets of brick, the pallets projecting beyond the ends of the table, and a tilting platform connected with said table and arranged to elevate the table and pallet, said *platform' -being tilted by the'weight of the workman step 6. combination, with a suitable frame having sheaves, of cable' conveyers operating therein, a tilting *table' normally in an inclined position andadapted to receive a pallet loaded with bricks, the ends of the pallet projecting beyond the ends of said table, means for raising said table and its load above the level of said conveyers, and the weight of the brick causing the table to assume a horizontal position when raised, whereby the pallet will be deposited upon the conveyors when the table returns to its normal position.

In witness whereof, I have hereunto set my hand this 12th day of March 1907.

FRANK S. PECK.
